0942777075.txt written by Phil Jones, the centre’s director, in 1999 "I've just completed Mike's Nature [the science journal] trick of adding in the real temps to each series for the last 20 years (ie, from 1981 onwards) and from 1961 for Keith's [size=4]to hide the decline."[/size] 1177423054.txt From: Ben Santer <[email protected]> To: [email protected] Subject: Re: FYI Date: Tue, 24 Apr 2007 09:57:34 -0700 The bottom line here is that observational data are frequently "messy". They are not the neat, tidy beasts Mr. Keenan would like them to be. 2

This holds not only for surface temperature measurements. It also holds - in spades - for measurements of tropospheric temperature from MSU and radiosondes, and for measurements of ocean temperatures from XBTs, profiling floats, etc. We would like observing systems to be more accurate, more stable, and better-suited for monitoring decadal-scale changes in climate. You and Kevin and many other are actively working towards that goal. The key message here is that, despite uncertainties in the surface temperature record - uncertainties which you and others in the field are well aware of, and have worked hard to quantify - it is now unequivocal that surface temperatures have warmed markedly over the past 100 years. Uncertainties in the station histories do not negate this basic message. 1255352257.txt From: Kevin Trenberth To: Michael Mann <[email protected]> Subject: Re: BBC U-turn on climate Date: Mon, 12 Oct 2009 08:57:37 -0600 Cc: Stephen H Schneider <[email protected]>, Myles Allen , peter stott , "Philip D. Jones" , Benjamin Santer <[email protected]>, Tom Wigley <[email protected]>, Thomas R Karl , Gavin Schmidt , James Hansen <[email protected]>, Michael Oppenheimer Hi all Well I have my own article on where the heck is global warming? We are asking that here in Boulder where we have broken records the past two days for the coldest days on record. We had 4 inches of snow. The high the last 2 days was below 30F and the normal is 69F, and it smashed the previous records for these days by 10F. The low was about 18F and also a record low, well below the previous record low. This is January weather (see the Rockies baseball playoff game was canceled on saturday and then played last night in below freezing weather). Trenberth, K. E., 2009: An imperative for climate change planning: tracking Earth's global energy. Current Opinion in Environmental Sustainability, 1, 19-27, doi:10.1016/j.cosust.2009.06.001. [1][PDF] (A PDF of the published version can be obtained from the author.) The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't. The CERES data published in the August BAMS 09 supplement on 2008 shows there should be even more warming: but the data are surely wrong. Our observing system is inadequate. That said there is a LOT of nonsense about the PDO. People like CPC are tracking PDO on a monthly basis but it is highly correlated with ENSO. Most of what they are seeing is the change in ENSO not real PDO. It surely isn't decadal. The PDO is already reversing with the switch to El Nino. The PDO index became positive in September for first time since Sept 2007. see [2]http://www.cpc.ncep.noaa.gov/products/GODAS/ocean_briefing_gif/global_ocean_monitoring_c urrent.ppt Kevin Michael Mann wrote: extremely disappointing to see something like this appear on BBC. its particularly odd, since climate is usually Richard Black's beat at BBC (and he does a great job). from what I can tell, this guy was formerly a weather person at the Met Office. We may do something about this on RealClimate, but meanwhile it might be appropriate for the Met Office to have a say about this, I might ask Richard Black what's up here? 3

The Matlab script plotcld.m allows comparison of scatter diagrams, these are fed from example data files manually extracted from the cloudreg.log file after varying the duplicate limit and/or strategy. Showed Phil - and now sidetracked into producing global mean series from the 3.0 parameters (DTR first). OK, got cloud working, have to generate it now.. but distracted by starting on the mythical 'Update' program. As usual, it's much more complicated than it seems. So, let's work out the order of events. May 2007 e-mail from Phil Jones that Ben Santer is replying to in 1178107838.txt. Jones says: As a side issue , the disappearance of sea ice in the Arctic is going to cause loads of problems monitoring temps there as when SST data have come in from the areas that have been mostly sea ice, it is always warm as the 61-90 means are close to -1.8C. Been talking to Nick Rayner about this. It isn’t serious yet, but it’s getting to be a problem. In the AR4 chapter, we had to exclude the SST from the Arctic plot as the Arctic (north of 65N) from 1950 was above the 61-90 average for most of the years that had enough data to estimate a value.

From: Phil Jones To: "Michael E. Mann" <[email protected]> Subject: HIGHLY CONFIDENTIAL Date: Thu Jul 8 16:30:16 2004 Mike, Only have it in the pdf form. FYI ONLY - don't pass on. Relevant paras are the last 2 in section 4 on p13. As I said it is worded carefully due to Adrian knowing Eugenia for years. He knows the're wrong, but he succumbed to her almost pleading with him to tone it down as it might affect her proposals in the future ! I didn't say any of this, so be careful how you use it - if at all. Keep quiet also that you have the pdf. The attachment is a very good paper - I've been pushing Adrian over the last weeks to get it submitted to JGR or J. Climate. The main results are great for CRU and also for ERA-40. The basic message is clear - you have to put enough surface and sonde obs into a model to produce Reanalyses. The jumps when the data input change stand out so clearly. NCEP does many odd things also around sea ice and over snow and ice. The other paper by MM is just garbage - as you knew. De Freitas again. Pielke is also losing all credibility as well by replying to the mad Finn as well - frequently as I see it. I can't see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow - even if we have to redefine what the peer-review literature is ! Cheers Phil Mike, For your interest, there is an ECMWF ERA-40 Report coming out soon, which shows that Kalnay and Cai are wrong. It isn't that strongly worded as the first author is a personal friend of Eugenia. The result is rather hidden in the middle of the report. It isn't peer review, but a slimmed down version will go to a journal. KC are wrong because the difference between NCEP and real surface temps (CRU) over eastern N. America doesn't happen with ERA-40. ERA-40 assimilates surface temps (which NCEP didn't) and doing this makes the agreement with CRU better. Also ERA-40's trends in the lower atmosphere are all physically consistent where NCEP's are not - over eastern US. I can send if you want, but it won't be out as a report for a couple of months.

Our chapter and figs (including 6.10) make it clear that it is unlikely any multi-decadal period was as warm as the last 50 years. But, that said, I do feel your are right that our team would not have said what the TAR said about 1998, and thus, we should delete that second sentence. any other thoughts team? jones-foiathoughts.doc Options appear to be: 1. Send them the data 2. Send them a subset removing station data from some of the countries who made us pay in the normals papers of Hulme et al. (1990s) and also any number that David can remember. This should also omit some other countries like (Australia, NZ, Canada, Antarctica). Also could extract some of the sources that Anders added in (31-38 source codes in J&M 2003). Also should remove many of the early stations that we coded up in the 1980s. 3. Send them the raw data as is, by reconstructing it from GHCN. How could this be done? Replace all stations where the WMO ID agrees with what is in GHCN. This would be the raw data, but it would annoy them.

Gavin and I are going to be careful about what comments we screen through, and we’ll be very careful to answer any questions that come up to any extent we can. On the other hand, you might want to visit the thread and post replies yourself. We can hold comments up in the queue and contact you about whether or not you think they should be screened through or not, and if so, any comments you’d like us to include. You’re also welcome to do a followup guest post, etc. think of RC as a resource that is at your disposal to combat any disinformation put forward by the McIntyres of the world. Just let us know. We’ll use our best discretion to make sure the skeptics dont’get to use the RC comments as a megaphone…
